What a difference color and gilding make! I have a pair of plates in this pattern with much less color added. The pattern can be found in several different colorways, and has two names: "Canton" or "Chinese Mountain".
"Canton" is the factory name, found on patterns in the second Factory pattern book, watermarked 1832 and 1834. Information from the Mason's Collectors Club states that "like many of the patterns from this period, numerous variants exist. The variations are mostly in coloring. The mark on the back dates this plate 1820-1830.
This 8-3/4" shaped plate is in excellent condition. There are no chips, no cracks, no crazing and no repairs. It rings when tapped.
